Transmission Line Distributed Fault Location Device

I. Product Description:

Transmission Line Distributed Fault Location Device is an efficient and reliable monitoring system that can monitor the operating status of transmission lines in real-time, quickly detect and locate faults, and provide early warning and protection functions. It mainly consists of hardware and software components. The hardware part includes monitoring servers and line fault location devices, while the software part includes monitoring software. The system uses distributed fault location technology to monitor the electrical status of transmission lines online, detect and locate faults in real-time, and provide early warning and protection functions.

II. Working Principle:

Transmission Line Distributed Fault Location Device operates based on the operational characteristics of the power system and the features of fault occurrences. The line fault location device is installed on the conductor, obtaining working power through inductive energy harvesting, accurately collecting line power frequency current and traveling wave current waveform data, and transmitting it back to the backend data center via wireless methods such as 4G/5G. The monitoring server runs monitoring software, accessing the Internet to retrieve data collected by the fault location device, and performing functions such as displaying, analyzing, processing, storing, and printing reports of the collected line current data. The system uses sensors distributed along the transmission lines to collect and transmit parameters such as voltage and current in real-time, monitoring their electrical status. Once abnormal conditions occur, such as overload, short circuit, or grounding faults, the system immediately issues an alarm.

III. Product Functions:

1. Determine the fault section based on power frequency fault current

2. Implement precise traveling wave location within the determined fault section

3. For transmission lines with complex network structures, install distributed fault diagnosis devices at branch points to divide the complex network into simpler single-line structures

4. Identify the causes of faults, enabling discrimination between lightning and non-lightning faults. It can also identify lightning strikes on ground wires, towers, and conductors without tripping

IV. Technical Parameters:

1. Ambient Temperature: -40℃ to +85℃

2. Relative Humidity: 0 to 100% RH

3. Atmospheric Pressure: 86 kPa to 106 kPa

4. Storage Temperature: -40℃ to +85℃

5. Wind Speed: 0 km/h to 100 km/h

6. Line Load: System coupling power extraction normal working current range 20 to 1000 A

7. Compatibility: Can withstand 500 kV strong electric and magnetic fields, with reliable and stable electromagnetic compatibility

V. Summary:

Transmission Line Distributed Fault Location Device can monitor the working conditions of transmission lines in real-time, quickly and accurately detect and locate faults, and provide early warning and protection measures, thereby effectively reducing losses caused by transmission line faults. The application of this system can effectively ensure the safe and stable operation of transmission lines and improve the reliability and economy of the power system. With continuous technological advancements and increasing application demands, it is believed that this system will play an even more important role in future power systems.
